Calculate the net formal charge of this species HNO3?

Answer 1

5 atoms in total: 1hydrogen, one nitrogen, and three oxygens

Answer 2

The formal charge of HNO3 is 0 because the charge on NO3 is -1 and the charge on H is always +1.

formal charge of an atom in a bond is measured by the number of electrons in it's last energy level.for an example Nitrogen has 5 electrons in it's last energy level.and when calculating the net formal charge, if the number of electrons in the last energy level of any atom increases,as electrons have a negative charge -1 should be added for each increased electron.

as an example in (NO3)^- nitrogen has contributed only 4 electrons to create bonds with oxygen as each bond is created sharing one electron from each atom.so there's a decrease of electrons in the last energy level of nitrogen.so it gets a +1 charge as it lacks one electron.

but if we consider the 3 oxygens around the nitrogen atom,one has 6 electrons which is the correct number of electrons in it's last energy level.but the other two has 7 which gives -1 charges for each atom.

and the total of all these charges equals to -1 which is the net formal charge of NO3.

Answer 3

To calculate the net formal charge of HNO3, you need to consider the valence electrons and the bonding in the molecule. The hydrogen atom has a formal charge of +1, the nitrogen atom has a formal charge of 0, and each oxygen atom has a formal charge of -1. Therefore, the net formal charge of HNO3 is +1 (from hydrogen) + 0 (from nitrogen) + 3*(-1) (from the three oxygen atoms) = 0.

Answer 4

Well the net charge of NO3 is -1 and the charge on H is +1 soo -1 + 1= 0!

Answer 5

Two ions are found.Cation is H+ and anion is NO3-.

Answer 6

-1

Answer 7

negative 1
